RAILROAD-TIE PLATE.

Application filed November 20, 1911.

7) all whom it may concern lie it known that 1, JAMES N. CHAPMAN, acitizen of the United States, residing at hiingman, in the county ofMohave and State of Arizona, have invented a new and useful Railroad-TiePlate, of which the following is a specification.

This invention relates to plates for supporting and securing railroadrails in place on the ties, and the main object of the in vention is toprovide a plate for this purpose of simple and cheap construction whichwill give a firm connection between the rail and tie.

A further object of the invention is to provide improved means forfastening the plate to the tie in such manner as to prevent displacementof the plate on the tie, but to permit the removal of the rails from theties, when required, without undue expense.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate an embodiment of the invention, andreferring thereto Figure 1 is a perspective of a portion of the track,showing the tie plates thereon, constructed in accordance with myinvention. Fig. 2 is a vertical section through a tie, showing the platein place thereon. Fig. 3 a vertical section on line 00-U in Fig. 2. Fig.1 is a vertical section on line w---w' in Fig. 2, partly broken away.Fig. 5 is a perspective of the tie plate.

1 designates the tie which may be of wood or other suitable material,and 2 the rails which are supported on the ties by means of the tieplates 3. Said tie plates are formed of flat plates of iron or othersuit-- able material adapted to extend under the foot of the rail andproject beyond each end thereof. In the portion of the tie plate whichprojects beyond the outside of the rail is formed a perforation 5 forreceiving a spike (l for engaging with the outside lower flange of therail for holdii g the rail. and plate in position on the tie. ()n theportion of the tie plate on the inside of the rail is provided aprojection 7 having a shoulder 7 adapted to extend over the inner flangeof the rail to firmly engage the same, said projection being secured tothe tie plate by any suitable means, for example, by a rivet formed of ashank 8 extending from the Specification of Letters Patent.

head or button through, a perforation 9 in the plate and. upset at itsinner end. The tie plate is also provided at its inner portion with aflange 10 extending downwardly at one edge so as to engage and lieagainst the side of the tie 1, said downwardly extending flange 10having one or more perforations 11 for receiving spikes 12 driven intothe side of the rail.

The tie plates are put in place on the tie, preferably in pairs with theflanges 10 extending from the two plates of each pair extending down onopposite sides of the tie,

and the plates are shoved into position so that the projection 7thereon, engages over the inside flange of the ail. The several spikes(3 and 12 being then driven into place, hold the tie plate firmly inposition on the tie. The spikes 12 driven through the perforations inthe flange 10 into the side of the tie, hold the tie plate firmly fromvertical. vibration or upward displacement, and the outside spikes 6hold the rail in firm engagement with the inside fastening means 7 aswell as holding the outer portions of the rail and tie plate firmly downonto the tie.

The head or projection 7 on the tie plate has a flange or shoulder 13extending over and engaging the tie plate on the side opposite toshoulder 7, to resist bending action on the head by upward pressure ofthe rail flange.

in case it is desired to remove a rail it is only necessary to draw thespikes 6 on the outside of the rail, whereupon the rail may be freelyslipped from the heads or projections 7 on the inside.

in the operation of a railroad it is found in practice that theloosening of the ordinary spikes is mainly, if not altogether, confinedto the spikes on the inside of the rail, the tendency of the movement ofthe train, for example, in passing around curves 011 a high speed, or inthe lurching of the train from side to side, is to overturn the railfrom. the inside, lifting the inner flange and pulling or loosening thespikes on the in side of the rail. By providing the plates extendingunder the rail with projections extending over the inside of the railany such action is eliminated, as the over-turning tends to lift theprojections at the inner ends of the plates and requires the lifting ofthe entire rail which is prevented by the weight of the train. On theother hand, there is little or no tendency to lift or draw the spikes onthe outside, and by utilizing driven spikes instead of plate clamps onthe outside of the rail, I am able to remove the rails readily asstated, for repairs.

'Moreover, with this constructionlthe same spikes that fasten'down theouter side of the ing a downwardly extending flange at the end on oneside thereof and at right angles thereto and the plane of said flangebeing at right angles to the line of the rail, resting against the sideof the tie, said downwardly projecting flange having orifices, nailsextending through said orifices into the tie, the outer projectingportion of said plate having a perforation, a spike extending throughthe perforation into the tie and engaging the flange of the rail, theinner projecting portion of the plate having a projection rivetedthereto.

In testimony whereof, I have hereunto set my hand at Kingman, Arizona,this 13th day of November, 1911.
